Majorbookworm 10 Posted June 25, 2013 Hi there, Im not sure if this is the right place to ask this, so my apologies if this is the case. I recently bought a new computer and have copied ArmA 2 and Operation Arrow head over to it, but can't seem to get them to play as a single game. I originally bought OA as a standalone retail copy, before later purchasing vanilla ArmA 2 on steam. On my old laptop they worked fine as a single program, but don't seem to be aware of each other on my new one. Does anyone know what I need to do to get them working properly? I simply copied the files on an external hard-drive when moving the game, if that is relevant to my problem. Thanks. Share this post Link to post Share on other sites
MissileMoose 10 Posted June 25, 2013 The easiest way to get everything working again would be to reinstall Arma 2, then Operation Arrowhead to the same directory. When copying the files over, you missed additional configuration in the registry, which I'm fairly certain is required to run Combined Operations. Take a look at this thread if you don't wish to reinstall. Share this post Link to post Share on other sites
